area. This fully up-to-date textbook on microperimetry, written by leading experts in the field, will also serve as an atlas and diagnostic reference. It is designed for use by both ophthalmologists and optometrists in daily clinical practice and clinical research, and the contents thus range from basic technical information to the most advanced clinical applications. Past and current microperimetry techniques are reviewed, and the role of microperimetry in the context of multimodal imaging scenario is explained. The full range of clinical applications is then discussed, including age-related macular degeneration, diabetes, myopia, retinal dystrophies, disorders of the vitreoretinal interface, inflammatory chorioretinal diseases, toxic retinopathies, glaucoma, and low vision.Lens Epithelium and Posterior Capsular Opacification
By Frank J. Lovicu, Shizuya Saika, Liliana Werner. 2014
This book is the first to summarize the current knowledge of the cell biology of lens epithelial cells in relation…
to and in the development of posterior capsular opacification (PCO). PCO remains the most common long-term complication of modern cataract surgery, occurring months or years after cataract surgery, unlike most other complications that tend to arise during or soon after the procedure. Opacification of the posterior capsule appears to be linked to lens epithelial cells that are left behind in the eye during cataract removal. These cells proliferate, migrate across the posterior lens capsule, and undergo changes that result in fibrous or pearl-type opacities in the capsule. The first section of the text explains the molecular mechanism and biology of lens epithelial cells that lead to the incidence of PCO. In the second part, in addition to a description of the mechanism and pathological condition of PCO, surgical methods and devices for preventing PCO are discussed in detail. Lens Epithelium and Capsular Opacification will benefit not only young clinical residents and junior researchers, but also established faculty in the clinical or basic academic field.Optic Nerve Disorders
By Jane W. Chan. 2014
Optic Nerve Disorders: Diagnosis and Management, Second Edition, is a thoroughly revised and updated reference, including new information on diagnostic…
techniques such as genetic testing for hereditary optic neuropathies, new data on toxic/drug-related optic neuropathies and recent data from clinical trial studies. Additional novel therapies, including stem cell therapies, the use of nanotechnology and gene therapies are featured highlights, as is spectral domain optical coherence tomography (OCT) for imaging of the optic nerve. The way in which OCT is used in differentiating optic nerve disorders from other retinal disorders and how OCT is used in monitoring the course of the disease, is also discussed. This practical reference focuses on common optic nerve disorders. It addresses diagnosis, pathophysiology, management and prognosis and is written in a clear, concise style for quick, easy reference in the clinic. With additional color photographs to better illustrate the material, the second edition will prove to be the go-to reference for ophthalmologists, neurologists and neurosurgeons working with optic nerve disorders.Microgravity and Vision Impairments in Astronauts
By Erik Seedhouse. 2015
Recent missions on board the International Space Station have revealed previously unreported physiological consequences of long duration space flight, particularly…
in eyesight, and in this Brief Dr. Seedhouse reviews the existing theories on what causes this degeneration and how long it will last. Notably, 60% of long-duration crews have reported subjective degradation in vision, a clear indication that further study is necessary before astronauts embark on even longer-term space missions. Decreased near-visual acuity was reported in 46% of ISS/Mir crewmembers, resulting in a change of up to 2 dioptres in their refractive correction. It is possible that ophthalmic changes have been present since the first days of spaceflight, but had been attributed to other causes; this approach to the issue as well as other hypotheses are all presented in full to give a broad foundation of the existing knowledge on the topic. The changes have occurred at various times during a mission with varying degrees of visual degradation. Some cases resolved on return to Earth, but several crewmembers have not regained pre-flight visual acuity, indicating the damage may be permanent. One explanation of the syndrome has been attributed to hyperopic shift due to aging, but onboard analysis techniques, including visual acuity assessments, retinal imagery, and ultrasound examination of the eye, has led to the acceptance of a wider syndrome. In addition to vision changes, studies have reported flattening of the globe, swelling of the optic disc (papilledema), choroidal folds in the retina, swelling of the optic nerve sheath, and visual field defects. It is widely hypothesized that this spectrum of symptoms may be explained by an elevation of intracranial pressure (ICP). Establishing the provenance of this medical problem, monitoring its occurrence and resolving the symptoms for future long term space missions is a key challenge for space medicine. With this book, readers have an entry point for understanding the full scope of the problem and its possible origins.Uveitis: An Update
By Jyotirmay Biswas, Parthopratim Dutta Majumder. 2016
This book on recent advances in uveitis provides readers with up-to-date and clinically-relevant information on 18 topics that are indispensable…
for everyday practice. This book is meant for bridging the gap between recent developments and their incorporation into clinical use. Written by global experts, the topics cover advances in diagnosis and treatment of distinct clinical varieties of uveitis. Additionally, the chapter on imaging describes the various imaging modalities that aid clinching the diagnosis with greater accuracy. Role of corticosteroids, their mechanism of action and various routes of drug delivery too have been discussed in detail. Optimal use of various immunomodulators, their role, dose, mechanism of action, side effects, and monitoring during patient follow-up have been elucidated in easy-to-understand tables. There are two chapters on complications in uveitis, one on glaucoma and other on choroidal neovascularization. A chapter on pediatric uveitis highlights the challenges and provides guidance to manage this special population.Manual Small Incision Cataract Surgery
By Bonnie An Henderson. 2016
This book, in a concise format, explains how to perform manual small incision cataract surgery. The procedure is broken down…
into the chief elements and described in a step by step manner. Besides the description of the procedure, the book covers indications, necessary supplies, preparation, complication management, and postoperative care. The authors are experts from around the world, and the book will be of value both for surgeons new to this technique and for experienced surgeons who need a review of the procedure. While phacoemulsification surgery has now become the standard of care, understanding how to perform manual extracapsular cataract extractions competently is crucial when faced with complications during phacoemulsification surgery, when operating in a region of the world without access to phacoemulsification or femtosecond lasers, or when a manual approach may be a better choice for the patient.Image Analysis for Ophthalmological Diagnosis

By Gianluca Tosini, P. Michael Iuvone, Douglas G. Mcmahon, Shaun P. Collin. 2014
Daily rhythms are a ubiquitous feature of living systems. Generally, these rhythms are not just passive consequences of cyclic fluctuations…
in the environment, but instead originate within the organism. In mammals, including humans, the master pacemaker controlling 24-hour rhythms is localized in the suprachiasmatic nuclei of the hypothalamus (SCN). This circadian clock is responsible for the temporal organization of a wide variety of functions, ranging from sleep and food intake, to physiological measures such as body temperature, heart rate and hormone release. Moreover, accumulating evidence suggests that dysfunction of the circadian rhythms due to genetic mutations or environmental factors (i. e. , jet-lag or shift work) contribute to the development of many pathologies, including sleep disorders, mood and affective disorders such as major depression, bipolar disorder and schizophrenia, as well as the risk of metabolic and cardiovascular disorders.
